Abstract

The utility model discloses an emptying anti-freezing solar water heater, which comprises a water tank, and an emptying pipe, an overflowing pipe and a water pipe which are arranged on the water tank, the water pipe extends a certain distance in the water tank, and the lowest end of the water pipe is lower than the communicating point of the overflowing pipe and the water tank, the top end of the emptying pipe is communicated with the water pipe, and a one-way valve is arranged between the emptying pipe and the water pipe, the conducting direction of the one-way valve stretches from the water pipe to the emptying pipe, and a spare pipe is arranged on the bottom of the water tank. Compared with the prior art, the emptying anti-freezing solar water heater has significant emptying and anti-freeze effects, and can early warn when water stored in the water tank is insufficient.

Description

Evacuation and anti-freezing solar energy

One, technical field

The utility model relates to a kind of solar energy, specifically has the solar water heater of evacuation and anti-freezing function.

Two, background technology

Solar energy is general huge numbers of families, solar energy especially in winter regular generation water pipe water freeze and can't use, existing antifreeze generally all be water pipe outer wrapping heat-insulation layer but weak effect; The patent No. is that 99216076.6 patent application discloses a kind of siphon anti-freezing solar water heater, its siphon pipe and upper and lower conduit directly communicate, thereby siphon pipe easily causes flowing water under the water siphon in the water heater and always can't arrive the purpose of evacuation and anti-freezing when emptying; Existing solar energy does not have the water alarm, and water is just found to bring great inconvenience to when the user especially has a bath when stream is empty.

Three, summary of the invention

The utility model provides a kind of evacuation and anti-freezing solar energy at above weak point, compares with prior art to have advantages such as evacuation and anti-freezing is effective, the water that can give warning in advance is few.

The technical scheme that its technical problem that solves the utility model adopts is:

A kind of evacuation and anti-freezing solar energy comprises that water tank, water tank are provided with evacuated tube, overflow pipe and upper and lower conduit; Upper and lower conduit gos deep into water tank one segment distance, and upper and lower conduit gos deep into the connectivity points that the interior least significant end of water tank is lower than overflow pipe and water tank; Evacuated tube is connected with upper and lower conduit on the top, is provided with check valve between evacuated tube and the upper and lower conduit, and the conducting direction of check valve is that upper and lower conduit is to evacuated tube.

During last water, cold water enters water tank through upper and lower conduit, and water flows out from overflow pipe when filling it up with; When temperature reduction needs are antifreeze, open exhaust-valve and upper hose on the evacuated tube, current flow out the current sky in two pipes from two pipes, thereby reach the purpose of evacuation and anti-freezing; In the time will using, close the exhaust-valve on the evacuated tube, go up then and open upper and lower conduit after the air emptying of upper and lower conduits such as water then and use and get final product.

Above-mentioned evacuation and anti-freezing solar energy, the bottom of water tank is provided with standby pipes, and the standby pipes position is lower than upper and lower conduit and gos deep into the interior least significant end of water tank, and the standby pipes other end is communicated with upper and lower conduit through valve.

When using the hot water of the sun, when its horizontal plane is lower than the least significant end of upper and lower conduit in water tank, this moment, upper and lower conduit did not have water to flow out, play the low purpose of early warning water water level, the water valve that can open on the standby pipes continues to use hot water, this function is convenient and practical, is especially using the solar energy Shi Buhui that has a bath the phenomenon of hot water to occur after a bath not having.

Four, description of drawings

Fig. 1 is a structural representation of the present utility model.

Five, the specific embodiment

The following correlation technique content of not addressing all can adopt or use for reference prior art.

As shown in Figure 1, a kind of evacuation and anti-freezing solar energy, comprise water tank 1, the top of water tank 1 is provided with steam vent, one side of water tank 1 is provided with evacuated tube A1 and upper and lower conduit A2, both are connected by check valve 2 at the most significant end of upper and lower conduit A2, and the conducting direction of check valve 2 is that upper and lower conduit A2 is to evacuated tube A1; The bottom of water tank 1 is provided with a position and is lower than the standby pipes A3 that upper and lower conduit A2 is positioned at the minimum point of water tank 1 part, and the described standby pipes A3 other end is communicated with upper and lower conduit A2 through valve B4.The opposite side of water tank 1 is provided with overflow pipe A5.

During use, heat-insulation layer on the outer wrap of solar water heater connects as figure.

During the water tank water filling, open cold valves B3, valve-off B1, B2, B4, the water of running water pipe A4 then close water valve B3 when overflow pipe A5 there are flowing out in upper and lower conduit A2 enters water tank 1, and add water and finish this moment, and be full of water in the upper and lower conduit A2 this moment.

When outdoor temperature was higher than zero degree use hot water, valve B1, B3, B4 were in closed condition at this moment, open valve B2, and then under the current in the upper and lower conduit A2, because siphonage, the hot water in the water tank 1 passes through upper and lower conduit A2 outflow.

When being lower than zero degree, outdoor temperature need carry out when antifreeze, after last water process is finished valve B1, B2 are opened simultaneously, shut off valve B3, B4, because the air of evacuated tube A1 enters upper and lower conduit, the water of upper and lower conduit A2 flows out along upper and lower conduit A2, thereby thereby antifreeze effect is played in the water emptying among the upper and lower conduit A2.

During antifreeze use hot water, open B3 valve, shut off valve B1, B2, B4, water in the cold water pipe A4 injects in the water tank through the water pipe A2 that reaches the standard grade and with the gas emptying of water pipe, this moment shut off valve B3, open valve B2, the hot water in the water tank 1 flows down through upper and lower conduit A2, the B1 valve is opened after finishing using again, antifreeze effect is played in water nature emptying among the upper and lower conduit A2.

In the use, when the water in the water tank 1 is lower than the least significant end of upper and lower conduit A2, anhydrous outflow among the upper and lower conduit A2, thereby play the effect of water alarm, open water valve B4 this moment, water in the water tank 1 flows out by standby pipes A3 and continues to use, and the back of finishing using gets final product for the solar energy water-filling, has avoided especially anhydrous embarrassment when shower is not intact.
